Farmers often face a lot of confusion when it comes to applying the right dose of fertilizer for their crops. One such crop is custard apple. Custard apple, also known as Sitaphal or Sharifa, is a tropical fruit that is widely grown in India. It is a nutrient-rich fruit that yields a good harvest when grown under the right conditions. However, applying the right amount of fertilizer can make all the difference between a good harvest and a great harvest.
When a farmer is planning to grow custard apple, they must first understand the nutritional requirements of the plant. Custard apple requires a balanced supply of nitrogen, phosphorus, potassium, and micronutrients like calcium, magnesium, and sulfur. Applying too little fertilizer can result in slow growth and stunted fruits. On the other hand, applying too much fertilizer can lead to burning of plant foliage, reduced yield, and excess vegetative growth.
To determine the right fertilizer dose for custard apple, farmers must consider several factors such as soil conditions, climate, and crop age. For young plants, a dose of 200 grams of nitrogen, 50 grams of phosphorus, and 200 grams of potassium per tree annually is considered to be sufficient. As the tree starts bearing fruit, the fertilization rate can be increased to 400 grams of nitrogen, 80 grams of phosphorus, and 400 grams of potassium per tree annually. Farmers can also use organic fertilizers like compost and vermicompost, which can provide all the essential nutrients required for the growth and development of the plant.
Apart from the dosage, farmers must also focus on the timing of fertilizer application. The best time to fertilize custard apple is during the monsoon season when the soil is moist and the tree is actively growing. Fertilizers should be applied at a distance of 1-2 feet away from the trunk and should be mixed with the soil.
In conclusion, applying the right dosage of fertilizer is crucial for a good harvest of custard apple. Farmers must understand the nutritional requirements of the plant, consider soil conditions, climate, and crop age, and apply fertilizers at the right time and in the right quantity. By doing so, they can ensure healthy growth, increased yield, and a profitable harvest.
